of Ohio, have invented certain new and useful:

Improvements in Street-Cleaning Machines,

of which the following is a specification.

This invention relates to that class of street cleaning machines in which an endless or continuous sweeping device, consistin of a plurality of brooms mounted upon end ess flexible elements dirt from the surface of the ground over an inclined-floor orconveyer bed into a receptacle which may be in the nature of a wagon The objects of the invention are to simplify' andimprove the construction and operation of-this class of machines, and with pointed out in the claims.

these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arran gement and combination of parts which'will be hereinafter fully described an particularly In the accompanying drawing'has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details thereinexhibited,

and that changes, alterations and modificai tions within the scope. of theinvention-may be resorted to when desired.

In the drawings, Figure l'is a side elevation of a street cleaning machineconstructed inaccordance with the invention; Fig. 1 is -a detail View, in elevation, of a portion of. the

rear end of the machine. Fig; 2 is a detail plan view of a portion of the endless broom illustrating the construction of the same. Fig. 3 is a perspective detail view of one of the individual broom members, detached.

Fig. 4 is a detail end view of one of the i-ndividual broom members. Fig. 5 is a detail plan view showing a discharge spout adapted to be used in connection with the machine.

Corresponding parts in the several'figures are denoted by like characters of referencel The improved machine is mounted for transportation u on the bed A of a suitably .constructed truc or vehicle supported upon transporting Wheels 1'1.

A suitable frame is mounted upon the bed' is employed to convey the provided with side uprights BB B and the ends of which are fitted in eyes 4 at the lower ends of the rods D D, the upper extremities'of which are screw-threaded, and extended through cap plates 5 which are mounted upon the upper ends of the uprights B the rods D are provided with nuts F having cranks Gwhereby they may be conveniently turned for the purpose of etfecting'vertical adjustment of the rods D and of theinclined fl'oor which is supported upon the cross bars carriedb'y said rods. The nuts F. have been shown as provided with flanges 6 operating inhooked guides 7 upon the cap plates 5.

' The flanges 3 are provided near their upper and lower ends with brackets K and K having slots LL for the passage of set screws 8 whereby said brackets are secured adjustably upon the flanges; thebrackets K at the upper ends of the flanges occli ying an-a proximately vertical position whi e the brac ets K near the lower ends of the flanges are approximately horizontal. These brackets aflord bearings for transverse shafts 9 carrying pulleys or band wheels JJ and sprocket wheels 0, the latter being disposed adjacent to the pulleys nearest the ends of the shafts. The pulleys J and sprocket wheels O sup ort the endless broom or sweeping mem er, which is composed of belts a traveling over the pulleys J, and endless chains .v traveling over the sprocket wheels 0; said chains being provided atintervals with laterally extending clamps or clips (Z, gripping the adjacent belts which are secured therebetween by means of fastening members such as rivets 10.

the belts aby means'of fastening members such as screws 11 that extend through the belts into the headset the broom. In this manner theendless belts, the endless chains, and the broom members are connected with each other so as to form the endless broom.

The endless broom is driven by means of a sprocket chain N. passing from a sprocket wheel 12 that is connected with one of the The threaded upper ends of.

A plurality of individual brooms, H, having bristles c are provided, said brooms being secured upondischarge spout 15, as shown in Fig. of the drawings, may be suitably connected with the upper end of the inclined fioor or con veyer bed.

From the foregoin description taken in connection with the awings annexed, the

operation and advantages of this invention 7 y will be readily understood. The endless broom will carrythe dirt and refuse in an upward direction over the inclined floor and dischar e the'same into the rece tacle W. Vertica adjustment of the swee ing apparatus may be'effected by means 0 the nuts F upon the su porting rods D; slack in the belts and chalnsof'the endless broom may be. taken uplly proper adjustment of the brackets K thus causing: the machine to i operate satisfactorily under all circumstances.

bearing eyes at t Having thus described the invention, what is claimed, is:

1. In a street sweeping machine a bed mounted upon transporting wheels, u rights rising from said bed and having cap p ates at their upper ends, screw-threaded rods operating through said cap plates and havin nuts upon the latter and provide with eir lower extremities, cross bars ssaaea en aging said eyes and operating in slots in the? uprights, a flanged floor or conveyer bed supported upon the cross bars, brackets con nected ad'ustably with said floor. near its upper an lower; ends, shafts jou'rnaledin said brackets, an endless broom supported upon said shafts, and means for transmitting motion to the latter from one of the transporting wheels of the machine.

2. In a street sweeping machine a bed mounted upon transporting wheels, u rights rising from said bed and having cap p ates at their upper ends, threaded rods extending through said ca plates, crank nutsmounte upon the threa ed rods and having flanges,

I guide hooks upon the cap plates engaging the nges of the nuts, cross bars supported by the threaded rods, an inclined floor mounted u on the cross bars, an endless broom suita ly connected with and supported by the floor, and means for driving the endless broom.

3. In a street s eeping machine ofthe class described an adjustably supported flanged inclined floor, supporting brackets connected therewith, shafts 'ournaled in the brackets and provided with and wheels and.

sprocket wheels, belts operating upon the band wheels, chains operating and connected with the belts, an individua brooms secured upon the belts.
